FIRE ESCAPE.

Application filed April 23, 1925. Serial No. 25,354.

This invention relates to an improved fire escape of the chute type and has for its object to provide a device of this character, which will convey persons from upper stories 6 to the ground floor, with least congestion and delay.

A further object of our invention is to provide a fire escape of the rolled edge chute type, that may be easily installed at 1 the side of a building and will be composed of few parts and one that will not easily get out of repair and may be used by all classes of people.

A further object of our invention is to provide a fire escape wherein the same will be particularly adapted. for use in school buildings, factories and the like, wherein a large number of people are to be discharged quickly and without delay.

A further object of our invention consists in the elevated horizontal seat provided for the entrance, to the fire escape slide, wherein users may enter the fire escape from an elevated seat arangement which connects directly into' the slide, obviating the necessity of their entrance into the slide from a position on line with the level of the platform entrance.

A further object of our invention consists in a new and improved bracket support disposed on the under side of the main slide and adapted to engage with the hinge band adapted to maintain the main slide in position.

A further object of our invention consists in the placing of a structural member along the rolled edge of the main slide member to afford additional rigidity thereto and to eliminate the possibility of the user of the slide becoming mangled from contacting with what would otherwise be the unsupported edge of the sheet forming the slide.

A further object of our invention consists in a new and simplified construction adapted to easy erection and one'that will be easily adapted to the wall structure of the building upon which the same is to be erected.

A further object of our invention consists in the simple and eificient structure created and one that will not easily get out of order.

A further object of our invention is to provide a railing around the same and a platform entrance and supporting means on the same.

While the primary object of our invention is for the purpose of use in schools, theatres, factories and the like yet the same may be used for the handling of packages and the like in warehouses, department stores, and other places wherein it is found desirable, or necessary, to bring materials to a lower level. When used for such purposes the same may be deposited upon the raised seat section which may be placed at the approximate carrying height of the worker depositing the same.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

The platform 3, extends from the wall of the building, conpletely across the upper oi' the entrance end oil the tire escape, and is adapted to support the users ot the same 153 they emerge through the opening 5, and

This we have tound, greatly inci'ci ses the speed, or the number of people, that be handled through our lire escape in a given time. To affort additional saiety to our new and improved lire escape we have proriced the usual rolled edge i), e

tending, the full length of the tire escape with a structural support along the edge. A substantial cistance is provided between the tire escape proper and the wall of the building, as shown at 10, in l, to permit of the tree and easy entrance from the building; on to the platform 8, and to the entrance into the slide ot the tire escape To further increase the rigidity of the escape and to lengthen the span, that the St me may be made between supporting brackets, we have supplied a structural member 11, to
